To. all @cham t may concern:

Beit known thatI, VALTnn P. MURPHY,

body setting up stresses tending to tear the sheets, which stresses, areconcentrated at the points where the sheets are held down on the roofsubstructure, and in part to the greater liability of the sheets to rustout under the clips on account of the constant frictionbetween the clipand sheet due to straining of the car, and the presenceof moisture andgrit under the clip.

My invention consists yin the provision of an improved means forattaching thesections of'a sheet metal covering of a car roof. to thecar structure, whereby there is obtained great freedom of movement ofthe sections with respect to the substructure and the rusting out of thesheets under or near the attaching means is overcome, and inV the lparticular construction, arrangement andv combination of the variousparts whereby this. isl accomplished, as more fully hereinafterdescribed and particularlypointed out in the claims.4

For the purpose of more fully illustrating -my invention I have appendedthe accompanying drawings, wherein like symbols are used to designatelike parts wherever they occur.

In the drawings Figurel l'is a partial section through the eaves of acar transverse to the longitudinal axis thereof; Fig. 2'is a sideelevation of my f improved roof clip; Fig. 8 isa front elevation of thesame, and Fig. 4: is a section through .the clip on' the line 4-4 ofFig. 2, showing a seaml in section arranged therein.

In the drawings 5 is'the side plate 'of .a car, 6 the side sheathing,the fascia, 8 the roof sheathing, 9 and 10 the metal roof sheetsconnected by the upstanding seam 22,

1,1 a hood clip forcovering the ends of the 55 vseam connecting, theroof sheets and securing the sheets loosely upon the roof substructure,

12a bolt for securing the cIip4 to the fascia, and 13 is a nail toprovide additional securing means for the clip. The clip itselfcomprises a base-portion 14 provided with a hole '15 for `the nail and asquare holef16I for the bolt and connected to the hood portion 17 byyokes'or straps 18 which yoke portions are spaced away from the underface of the base.-

portionsothat when the clip is applied to the car a spaceis left betweenthe fascia and the yoke portions, into which space the turned down ends19,01? the r'oof'sheet's eX- tend and in which they can have a limitedamount of play. The hood portion 17 has at the lower edges of its sidefaces-curved or dished flanges E20, which lflanges have eX- tensions 21projected beyond the open side 'of the hood.4 The inner ends of these,extensions 21 are spaced so far from the point of attachment of--theclip tothe fascia that in case the angle between theside and roof of thecar becomes more obtuse through any cause and there is any tendency forthe inner ends 'of the flanges to be jammed downv on the roof sheets,the result will be the bending of the clip at the yoke portions 18rather than the clamping 'of the roof sheets, due to the long leverageof the extremities of the flanges with respect tothe point of attach-4ment of the-clip.A These flanges on account of their arrangement andpeculiar 'conformation not only present a broad under surface free `fromsharp edges and so unlikely to cut the roof sheets but are spacedsufhciently. far apart so that in case'there is any tendency` for ktheclip, either through accident, or careless workmanship-'in its.application to the car, to turn upon the bolt 12, which would resultinbindingthe roof sheet under one of the flanges, this tendency is largelyovercome, and the likelihood of the roof sheet ,becomingy clamped frommovement on the substructure is much less than where the older type ofclip is used. More- 'over the wide spacing apart of the flanges 'enablesa space of 'at least the width of the seam to lbe left between the innerfaces of Iqo.

the hood and the seam onl either side thus" f providing adequate. roomfor movement of the roof sections longitudinally on the substructure.The spacing 'of the yokes 18 away .from the side of the car not onlyenables the turnedl down edges of theroof sheets to have free play overthe eaves, but

-enables the -front end of the hood lto be closed by the vfront sidewall 23 to prevent the weather from blowing into the open end of theseam," while anydirt or-water collecting beneath the hood portion canreadily escape -through the 4openin 24 below the front wall. Moreoverthe ront wall '28l is spaced away from the end of the seam, thusallowing the roof sheets considerable movelongitudinal axis of the car.

In applying the roof-clip to the ment onthe substructuretrans'verse tothe` car roof,

the workman, @after positioning the roof sheets upon thesubstructure,places the clip centrally over the seam and marks the placefor the bolt 12, then removes the clip and bores a hole through thefascia, side sheath-4 ing and side plate forthebolt. The. clip is thenreplaced in position and the bolt 12 is inserted and made fast. The nail13 is -then 'driven as an additional securing means. This methodofapplying the clip insures that the lianges 20 shall be spaced slightlyabove lthe roof sheets, and shall not bind the'm tightly, butfwillallowthe roof. sheets to move on the roof substructure. 'The clip onceproperly applied in'this inanner, ;there is very little "danger of itsbecoming knocked` sidewise along'the eaves so as to force one of theflangesto cut into the roof sheet un- 'der it, because of the provision.of the twoV points of attachment of the clip `to the sub` j structure,and the wide spacing of the ianges. Thelower surface of each flangebeing curved insures that even though the clip bc iinproperly'applied,or knocked out of place through accldent, 'the .contacting surfacebetween either iiange andthe roofv connected to each other by upstandingseams transverse to the longitudinal axis of the car, and extendin tothe eaves of the car, a
